Also did the big 3 with solid copper 2awg and now have no dimming with the volume cranked at idle (65amp alt)

PG RSD's are taking the rated 625 per speaker with no problems or distortion. I ran them for one hour at high volume, and still no issues More testing/wanging to come, and I will update this thread if I have any problems!

I haz no more audio $*** in my rig... it is all sitting in my living room
